I went on a Smashwords buying spree earlier in the week using VoucherCodes40 -- go Kobo bookstore for carrying Smashwords titles and letting the coupon appy!

I'm not sure to understand what you mean? Did you buy a book on Smashwords by using Kobobooks?
That seems interesting anyway

Edit: GeoffR, some countries seem to have more coupons than others :| and some stores provide more coupons than others. I've only received one email from Kobo with a discount so far. Books on board is emailing me maybe once a week
